i810 Driver and Flat Screen Problems

[samad26]

Hey guys,
I haven't been able to get X working properly. My entire screen appears stretched. I have a 19" flat screen panel. My video card is on an Intel 82945g. I am using the i810 driver. In Windows, the correct screen size is 1280x768 @ 60mHz (could also be 70mHz). When I change the "Mode" value to "1280x768." the screen still appears completely stretched. I've tried the resolution "1440x900," but even that doesn't work. When I use this resolution, my entire desktop does not appear. I have to move the mouse around to see various parts of the screen. For example. when I move the mouse to the bottom-left of the screen, the entire desktop scrolls in that direction. I've been looking at forums online, but I haven't been able to find a solution. I've tried adding output from the gtf program, but that doesn't help at all. Here is the relevant information from /etc/X11/xorg.conf:

Section "Module"
Load "i2c"
Load "bitmap"
Load "ddc"
#Load "dri" (I can't seem to get the DRI module to work with the i810 driver)
Load "extmod"
Load "freetype"
Load "glx"
Load "int10"
Load "type1"
Load "vbe"
EndSection

Section "Monitor"
Identifier "Acer AL1916W"
Option "DPMS"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "Generic Video Card"
Monitor "Acer AL1916W"
DefaultDepth 24
...
SubSection "Display"
Depth 24 Modes "1280x768" "1440x900" "1440x1440" "1280x1024" "1280x960" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480"
EndSubSection
EndSection

Any help will be greatly appreciated.

After much Googling around, I finally figured out the solution. Check out:

The 855resolution program will fix the stretched screen problems.

Just checking does your motherboard use shared memory for video
Mine did and I had the same problem with total loss of screen if resolution set too high .
I increases shared memory in the BIOS from 8 Meg to 12 Meg and the problem was fixed
